VEVOR Portable Induction Cooktop, 1500W Electric Induction Burner with 9 Temperature Settings, Countertop Induction Hot Plate with 4H Timer, 24H Reservation, Child Lock, Easy to Clean, for Cooking

Induction cooker MODEL:K1001-2 How can I reset the timer? It always shows up when I switch on the cooker. I cannot set it to zero at any time with any button. There is no hint in the manual. Best regards Frank
